[2015·重庆一中一诊]The African elephant, the largest land animal remaining on earth, is of great importance to African ecosystem (生态系统). Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big planteater, it largely shapes the forestandsavanna (稀树草原) surroundings in which it lives, therefore setting_the_terms of existence for millions of other animals that live in its habitat (栖息地)．
It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and
underbushes, and pulls branches off big trees. This results in numerousopen spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various
stages of growth that attract a variety of other plant eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations，the forests become suitable for large hoofed plant eaters to move around and for small plant eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.

[2015·西安下学期月考] With the development of society, the choice of food and drinks for children is more diversified than ever
before. However, every coin has two sides. Many facts suggest that children are overweightand the situation is getting worse, according to the statistics. I feel there are a number of reasons for this.
Some people blame the fact that we are surroundedby shops selling unhealthy，fatty foods, such as fried
chicken and ice cream, at low prices. This has turned out
a whole generation of grownups who seldom cook a
meal for themselves. If there were fewer of these restaurants then probably children would buy less
takeaway food.
There is another argument that blames parents for allowing their children to become overweight. I agree to this, because good eating habits begin early in life, long before children start to visit fast food shops. If children
are given fried chicken and chocolate rather than healthy
food, or are always allowed to choose what they eat, they
will go for sweet and salty foods every time, and this will
carry on throughout their lives.
There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers. Not only is this an
unhealthy pastime (消遣), it also gives them time to eat
more unhealthy food. What they need is to go outside and play active games or sports.
The above are the main reasons for this problem, and
therefore we have to encourage young people to be more active, as well as guiding them away from fast food shops
and bad eating habits.
本文是健康类短文，本文第一段是一个中心段，提出儿童肥胖的问题，在2,3,4段中分别给出一个原因。在文章最后一段进行了总结提出了解决问题的方法。
5．What is suggested by the author to deal with
“overw- eight”？
A．Blaming the shops selling unhealthy and fatty foods.
B．Asking young children to walk to school every day.
C．Living an active life and removing bad eating habits.
D．Not watching TV or playing computer games after school.
答案：C 考查推理判断。根据文章最后一段“The above are the main reasons for this problem, and
therefore we have to encourage young people to be more
active, as well as guiding them away from fast food shops
and bad eating habits.”可知作者给出的建议是要过着更为积极的生活而且要把一些不好的饮食习惯去除掉。故C项正确。
6．Which of the following shows the structure of the
whole text?
答案：B 考查篇章结构。本文第一段是一个中心段，提出儿童肥胖的问题，在2,3,4段中分别给出一个原因。在文章最后一段进行了总结提出了解决问题的方法。属于总分总的结构，故B正确。
7．The author writes the passage to________.
A．show people a social problem
B．provide facts for government
C．advise solutions to a problem
D．compare opinions with people
答案：C 考查推理判断。本文先提出一个问题：儿童肥胖；在2,3,4段中分析出现这一问题的原因，最后一段中提出对于这个问题的解决方法。作者写本文的目的是在于对一个问题的解决方法提出的建议。故C项正确。
8．The underlined word“diversified”in the first paragraph most probably means________.
A．various
B．difficult
C．expensive
D．available
答案：A 考查推理判断。根据本句“With the development of
society, the choice of food and drinks for children is more
diversified than ever before”可知现在的儿童在食物的选择方面很丰富，同时也带来了很大的问题。所以本词表示的是多种多样的；亦可根据diversity来猜测该词的意思与多样化有关，故A项正确。
1．overweight adj. 超重的；过重的
2．statistics n. 数据；统计
3．blame n．/v. 责备；归咎于
4．surround v. 包围，围绕
5．unhealthy adj. 不健康的
1．with the development of 随着……的发展
2．a number of 许多的；大量的
3．agree to 同意；接受
原文：Not only is this an
unhealthy pastime, it also gives them time to eat
more unhealthy food.(倒装句)
译文：这不仅仅是一种不健康的消遣方式，而且也给他们吃更多不健康食物的时间。
仿写：Not_only_has_she_been_late_three_times_in_the_past_ three_days,_she has also done no work.
她在过去的三天不仅迟到过三次，还没干一点活。
